606 | ============================================================================== | |
607 | ||
608 | In order to overcome the limitation of maximum number of registers | |
609 | supported, the hardware separates register into different groups called | |
610 | 'pages.' Each page is able to include up to 255 registers. | |
611 | ||
612 | The default page after power up is 0x82; therefore, if one has to get | |
613 | access to register 0x8301, one has to use following sequence to switch | |
614 | to page 0x83, then start reading/writing from/to offset 0x01 by using | |
615 | the register read/write sequence described in previous section. | |
616 | ||
617 | Page register reading sequence: | |
618 | ||
619 | 1. send 0xf3 PS/2 command to FSP; | |
620 | ||
621 | 2. send 0x66 PS/2 command to FSP; | |
